My invention relates to new and useful improvements in closures for containers and more particularly to one in which the cap retaining means may be readily removed without destroying the further usefulness-of the container. v I

An object ofthe invention is to provide a sealed container which may be economically manufactured; and which can be easily and.

readily opened without the use of .any tool and a 1 cap which, after the container is,

opened, may be satisfactorily used for closing the container while the contents are being used. a k

Another object of my invention is to make a container of the above type in which the cap has a friction seal with the container.

Another object of my invention is tomake such a container in which the retaining ring may be hollow and may be made of a plurality of turns of a spiral, such as a spiral spring.

Another object of my invention is to provide such a container with pointed projections .to hold the retaining ring up toward the mouth or opening of the container, and which tend to push the projecting handle of the retaining ring from the top of its surface, and down between such projections.

Another object of my invention is to make.

a retaining ring the handle. of which has a smaller cross sectional area projecting from between the container and ca than the-ring has between the container an cap.

Further objects and advantages will be apparent from the following description and the accompanying drawings:

Figure 1 is a partial cross sectional view of the spiral retaining ring between the container and cap.

Figure 2 is a front view with certain parts broken away.

Figure 3 is a cross sectional view on line 3-3 of Figure 1.

Figure a is a front view of the container.

Figure 5 is a partial front view of another modification of the retaining ring;

Figure 6 is a, cross sectional view of the modification shown in Figure 5, on line 6-6 of Figure 5.

Similar numerals refer to similar parts throughout the several views.

jacent its mouth. These projections are pointed as shown in Figure 6. for a purpose hereinafter to be described. Within the groove formed by these projections and the flared container top is a retaining ring 4 made of a plurality of turns of a spiral, such as a spiral spring. One end of this'spiral proj ectsbelow the projections 3 to form a handle 7 for the removal of the spiral. The other end of the spiral is coiled smaller and screwed into the larger end as shown in Figures 1 and 2. This construction makes the spiral practically a solid ring.

Placed within the container mouth is a cap. 5 having walls parallel to the walls of the container mouth and forming with them a friction seal. The outer edge of the cap is bent around the retaining ring as at 6, so that the retaining ring is pushed firmly against the container by the extreme lip of the cap and the retaining'ring thereby holds the cap firmly on the container.

In placing the retaining ring around the container body should the projecting portion of the handle 7 chance to rest upon the top of one of the projectionsB, the pointedncss of these projections as shown .in Figure 6 tend to make the ring creep around the container, so that the projecting part of the handle will npt be upon the projection but to one side 0 it.

In Figures 5 and 6 a retaining ring 9 having its handle 10 drawnto a smaller diameter than the ring is shown, otherwise the construction shown in these figures may be made substantially like that shown in the other figures.

The cap in Figures 1, 2 and 4 is removed by pulling upon the handle 7 which untwists the spiral and gradually it may be pulled out. In this modification the extreme lip of. the cap is not bent outward by theremoval of the ring, but the ring, rather, is distorted in its removal, v

vIn Figures 5 and 6 the cap is removed by pulling outwardly upon the handle 10 which bends the cap lip outwardly and by continually pulling downwardly and outwardly around the container the ring is removed and the lip is bent outwardly, and the cap may be then removed.

The retaining ring may be made of any material or of any cross section, its only requiremcnt being that it hold its form under the stresses to which it is subjected, and that it have suliicient tensile strength to be pulled out.

As many changes might be made in the above arrangements and as many variations might be made without departing from the scope of the invention, it is intended that all features herein described or shown in the accompanying drawings, shall be interpreted as illustrative, and that the invention be limited only by the following claims.

I claim:

1. In combination, a container, a cap thereon, a retaining ring comprising a plurality of turns of a spiral surrounding the mouth or opening of said container, the edge of the cap forming a bead surounding said ring laterally to the extent that the inner periphery of the extreme lip of the cap bearing on the ring is greater than the outer periphery of the container within said ring and less than the outerperiphery of the ring, said ring having a projecting handle by which to remove said ring. v

2. In combination, a container, a cap thereon, a retaining ring comprising a plurality of turns of a spiral surrounding the mouth or opening of said container, the edge of the cap forming a bead surrounding said ring laterally to the extent that the inner periphery of the extreme lip of the cap bearing on the ring is greater than the outer periphery of the container within said ring and less than the outer periphery of the ring, and a portion of said spiral projecting from said bead to form a handle by which to remove said rmg.

3. In combination, an open end container portion, a cap thereon, said container portion and cap being provided with adjacent surfaces forming a space having a contracted exit, a member disposed in said space of greater width facing said contracted exit than the width of the contracted exit, said member being hollow but firmly resisting lateral compression and shear, a projecting handle on said member of a thickness between said adjacent surfaces not greater than the width of the contracted exit, said member being adapted to be removed through said contracted exit.

4. In combination, an open end container portion, a cap thereon, said cap forming with the outer wall of the container portion a space having a contracted exit, a retaining member surrounding the open end container portion and disposed in said space of a great er width facing said contracted exit than the width of the contracted exit, a projection on the outer wall of the container portion immediatelybelow said member and said member having a handle projecting from, said space and to one side of said projection.

5. In combination, an open end'container portion, a cap thereon, said cap forming with the outer wall of the container portion a space having a contracted exit, a retaining member surrounding the open end container portion and disposed in said space of a greater width facing said contracted exit than the width of the contracted exit, a plurality of projections on the outer wall of said container portion immediately below said member, and said member having a handle projecting from said space and between said projections.

6. A retaining ring for holding a cap on a container, said ring. comprising a plurality of turns of a spiraland being adapted to be placed between the wall of the container and the edge of the cap, andby its resistance'to.

compression and shear, to hold the cap on the container, a strand of said spiral projecting from the path of said ring to form a handle by which to remove said ring.

7. A hollowretaining ring for holding a cap) on a container, said ring being adapted to e placed between the wall of the container and the edge of the cap, and by its resistance to compression and shear, to hold the cap on the container, said ring having a projecting handle of a thickness between the container and cap edge not greater than the thickness of the shell of the retaining ring, by which to remove said ring.

8. In a container, a cap therefor, a groove with a restricted opening formed by the container wall and the edge of the cap, a hollow retaining ring in said groove, which ring, by its resistance .to compression and shear, holds the cap on the container, said ring having a projecting handle of a thickness between the container and cap edge not greater than the thickness of the shell of the retaining ring, by whlch to remove said ring.

9. A container seam for the end of a container comprising, a container wall, a retaining ring surrounding the container wall near said end, said ring having a projecting handle, means projecting from said wall to hold said ring up toward said end, a cap having an outer down-turned wall partially surrounding said ring and firmly holding it against said container wall, the internal surface of said down-turned wall which partially surrounds the ring not being bulged outwardly where said handle projects, and the cap also having an inner outwardly facing wall engaging peripherally an inwardly facing Wall of the container.

10. A container seam for the end of a conring and firmly holding it against said container comprising, a container wall, a retaintainer wall, the internal surface of said downing ring surrounding the container wall near turned wall which partially surrounds the 10 i said end, said ring having a projecting hanring not being bulged outwardly where said 5 dle, means projecting from said wall to hold handle projects.
